me-tv-client throws blocking error

[doktor5000]

Using TVGo-DVB-T03
At the command line:

Code: Select all

I googled for this error, but what I found mostly were programming issues.

Do you use cauldron? Did you read https://wiki.mageia.org/en/Cauldron ?

[hviaene]

Yes,I use Cauldron, and I read the wiki. So, I'm not complaining, I just wanted to test this TV facility to its very end.

[doktor5000]

See your original thread and first make sure that the card is working.
Then rule out if it may be some cauldron issue with me-tv, and try some other alternatives (vlc, xawtv, mplayer, kaffeine [which may be broken too] or something else)

The device works with VLC.
With xawtv there is a problem with

Which seems strange to me, because an x86-64 installation

[doktor5000]

Can you try to run

Code: Select all

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so xawtv

Before make sure that you have libv4l-wrappers installed (or lib64v4l-wrappers if x86_64 install)

For me-tv, just tested on Mageia 4 and it runs just fine, so seems to be a cauldron problem.

[tarazed]

Slightly off-topic maybe but me-tv does not work for me on mga4. kaffeine and vlc were working consistently but are developing problems after my experiments with me-tv, like losing sight of the adapter.

$ setenv LOAD_PRELOAD "/usr/lib64/lib4l/v4l2convert.so xawtv"

That brought up the interface, which asked for the channels.conf file which I had recently generated using w_scan but the importing channels window came up empty and there was nothing in the channel selection window.
Ran xawtv by itself:

Something missing from my setup by the look of it, but what?

[doktor5000]

$ setenv LOAD_PRELOAD "/usr/lib64/lib4l/v4l2convert.so xawtv"
$ me-tv-client

Why did you run it like that?

For xawtv, it seems to be broken - best open a bugreport for that.

[tarazed]

tc shell. Your command would not work.
xawtv bug report upstream?

[doktor5000]

tc shell. Your command would not work.

semantic still seems wrong, even the name of the env. variable is different. Should be

Code: Select all

setenv LD_PRELOAD "/usr/lib64/lib4l/v4l2convert.so" xawtv

xawtv bug report upstream?

No, Mageia bug report.

[hviaene]

In the mean time, I'm on Mageia 5 Beta 2.
Here the me-tv-client works OK, no more error. But (and that was the same with VLC), I had to use the scan command to make a channels.conf file manually and feed that one into the programs.
And xawtv does not see the device, it just shows me the webcam, I cannot select any other devide in its settings.

[tarazed]

doktor5000: yes - I was being a bit sloppy.
Glad to see hviaene got me-tv working. I have used w_scan and scan with different output formats to no avail. Will stay with vlc if kaffeine dies eventually.
